Connecting a LINE Official Account lets your apps send and receive messages through it. You’ll need a LINE Official Account and access to the LINE Developers Console to copy a few credentials.
Just testing? You don’t need your own account yet—apps can send on a shared dev account in sandbox and preview with no setup (50 messages/day). Connect your own before going live. See the testing comparison.

​
Connect your account

1

Open Integrations

In your organization dashboard, go to Settings → Integrations and expand LINE. Click Connect LINE Official Account.
2

Copy your credentials from LINE

In the LINE Developers Console, open your account’s Messaging API channel and copy:
  • Channel ID
  • Channel secret
  • Channel access token (the long-lived token)
3

Paste them into Stardeck

Enter the three values (and an optional display name) and submit. Stardeck verifies them with LINE and adds the account to your list.
4

Set the webhook URL

Copy the webhook URL shown in the dialog and paste it into your channel’s Messaging API → Webhook settings in the LINE console, then enable “Use webhook.” This is what lets your account receive messages. See Receiving messages.
You can connect more than one Official Account—each appears as its own connection.

​
Grant the connection to your apps

A connection does nothing until you allow an app to use it.
1

Open Grants

On the connection, click Grants.
2

Add an app

Pick an app from your organization and grant it access. Repeat for each app that should use this account.
3

Set a default

If an app can reach more than one LINE account, mark one as the default (the star). The agent uses the default when you don’t name a specific account.

​
Build features

Once a connection is granted, open the app’s project chat and describe what you want: 
Send a LINE message to the customer when their booking is confirmed
The agent builds against the granted connection automatically. See What you can build.

​
Rotate credentials

If you regenerate your channel secret or access token in the LINE console, click Rotate on the connection and paste the new values. Stardeck re-verifies them, and your grants and defaults are preserved. (The account must stay the same—rotating can’t switch a connection to a different Official Account.)

​
Disconnect

Click Delete on a connection to remove it. Any app relying on it can no longer send or receive through that account, so re-point them to another connection if needed.
